One angle of a triangle is four times as great as a second angle. The third angle measures 5 degree more than twice the second angle. Find the measures of the angles.
Thank you! Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! let the second angle be x
first angle will be 4x
Third angle = 2x+5
The sum of angles of a triangle = 180 deg
x+4x+2x+5=180
7x+5=180
7x=180-5
7x=175
/7
x=25
second angle = 25 deg
first angle=4x=4*25=100 deg
Third angle = 2x+5=2*25+5=55 deg
